What is this?
Batching sends multiple SQL statements in one command/round trip to cut network chatter.
Why should you care?
ShopNest admin tools updating many statuses benefit from batches — carefully with transactions.
See it live — copy this example
Use a .NET console or API project with SQL Server LocalDB. Run dotnet run after pasting.
cmd.CommandText = @"
UPDATE Orders SET Status='Packed' WHERE Id=@Id1;
UPDATE Orders SET Status='Packed' WHERE Id=@Id2;";
cmd.Parameters.Add("@Id1", SqlDbType.Int).Value = 1;
cmd.Parameters.Add("@Id2", SqlDbType.Int).Value = 2;
Console.WriteLine(await cmd.ExecuteNonQueryAsync(ct));What happened?
- Fewer round trips.
- Still use parameters.
- Prefer TVPs/bulk for large sets.
- Wrap in a transaction when all-or-nothing.
Practice next
- Batch two updates.
- Compare 2 round trips vs 1.
- Add BEGIN TRAN in SQL for atomicity.
- Batch three ids.
- Fail second update and rollback.
Remember
Fewer round trips. Still parameterize. Tx when needed.
ShopNest pack wave
Ops marks a small set Packed in one batch.
Outcome: Less chatty than N updates.
